2.0.1　Submerged arc furnace

Submerged arc furnace（hereinafter referred to as SAF），also called resistance furnace，is a type of furnace which is used to produce ferroalloy by smelting ore through reduction method using carbon reducing agent through the utilization of arc heat and resistance heat of material，and its operation is continuous.

2.0.2　Electrode slipping

During smelting process，the electrode will be slipped downward with certain length at regular time intervals or according to furnace conditions considering electrode loss so as to maintain operation of electrode working end length.

2.0.3　Electrode hoisting

Electrode will be entirely hoisted through electrode brake.

2.0.4　Self-baked electrode The lumpy electrode paste will be baked into an entirety locally inside electrode shell utilizing the resistance heat generated by electric current.

2.0.5　Metallothermics

Metallothermics refers to a kind of technological process for producing ferroalloy by utilizing heat generated through chemical reaction in which metal with higher chemical activity is used for reduction of another type of oxide.

2.0.6　Shaking ladle process

This process is used for producing low carbon and medium carbon ferromanganese（Fe-Mn）and some other alloys.The ore，flux and liquid alloy which are preheated are charged into shaking ladle for shaking，and the charge will be molten by utilizing the sensible heat and latent heat of the charge to produce alloy through reduction reaction.
